I first sat down with winemaker Chris Phelps almost two years ago, diving into his remarkable journey. Having worked at the likes of Dominus, Caymus and Inglenook, it was chance – or maybe fate – that led him to establish his own wine label, Ad Vivum, in 2007.  He was sitting above a tank of just-fermenting fruit when he was struck by a “coup de foudre” – falling instantly for Sleeping Lady Vineyard, a site farmed by his good friend Larry Bettinelli. He bought the half-fermented must, and has continued to do so every vintage since.  The specific blocks that filled that tank sat up against the Mayacamas at the very top of the vineyard, which is the southernmost site in Yountville. Here, the vines are shielded from the blaze of the afternoon sun, preserving acidity and aromatics in the fruit, while a flow of underground water allows the site to thrive in even the driest of years. Each year, from just 1.5 acres of Cabernet Sauvignon, Phelps crafts another expression of the site.  The exact parcels have shifted very slightly over time. In 2007, the vines were all Clone 191 – the clone he felt was best on the site, but the block needed replanting so they started using fruit from an adjacent plot, planted with Clone 7. After a “carefully thought-out dance” balancing the two plots, the 2024 vintage marks a return to using fruit only from the original plot, now replanted with Clone 191 (and known as Clone 34, which is genetically identical to 191).  Phelps left his day job (working for other wineries) at the end of 2023, finally able to focus exclusively on Ad Vivum, as well as a newer project with his son Josh (Coil Wines). Although we’d tasted the current releases before, earlier this month we were able to taste a trio of back-vintages for the first time. They reinforced how special this site is, as well as Phelps’s talent when it comes to capturing it in bottle.  The three vintages we tasted were 2016, 2017 and 2018 – three very different years in Napa. All three, however, manage to combine great freshness with Napa polish – creating wines that are surprisingly approachable already.  2016 Ad Vivum  In Phelps’s words, 2016 was “a classic Napa vintage”; the weather was warm at the end of June, allowing the vines to focus on fruit ripening, while autumn brought cooler weather. Phelps harvested from 7th October, fermenting in 21% new French oak (the rest in stainless steel), with a total of 19 days on skins prior to maturation for 18 months in 65% new French oak. It has always had “a seamlessness”, Phelps noted, and that’s certainly true tasting the wine.  The nose offers sweet, dark fruit, graphite purity and hints of lifted florals as well as an herbaceous edge. The palate is linear and pure, with mouthwatering acidity and a savoury core of ripe fruit, sweet cassis and ripe tannins that provide a drying grip on the finish. Although the oldest of this mini-vertical, it almost feels the youngest and will certainly benefit from additional time in bottle. A blend of 56% Clone 7 and 44% Clone 191 Cabernet Sauvignon.   2017 Ad Vivum  The 2017 vintage is one that will forever be remembered for its wildfires in Napa, although fortunately Ad Vivum wasn’t impacted by them. After an early budbreak, the growing season was marked by three heatwaves – in mid-June, at the end of August and in mid-September. Having a cooler site, shaded from afternoon sun and with sufficient water reserves was key for Phelps. He harvested from 5th October, bringing in 55% Clone 191 and 45% Clone 7 Cabernet. It was fermented in 25% new French oak, spending 20 days on skins in total (Phelps noted how easily colour and tannin came in this hot vintage), before being aged 17 months in 70% new French oak.  The nose here is bright and perfumed, combining sweet dark fruit – black cherries and blackcurrant – with floral lift and pencil lead. There’s a glorious purity to the fruit here, which follows through onto the dense yet fresh palate, displaying a juicy elegance. There’s a satisfying chew to the tannins, firm yet velvet-like, framing the waves of fruit that flow towards to the long, saline finish. Mouthwatering and moreish, this is hard to resist now.  2018 Ad Vivum  Although the 2018 vintage in Napa started with relatively late budbreak, cooler, even temperatures made for a long growing season, and producing relatively plentiful yields – yet without any dilution, thanks to the extended season. Phelps harvested from 17th October, with the blend moving back towards around two thirds Clone 191 Cabernet from the original block and a third Clone 7. Fermented in 25% new French oak, Phelps left the 2018 on skins for 23 days – slightly longer than other vintages, feeling structured fruit needed more time to reach its potential, echoed with its maturation in 75% new oak for 20 months. Phelps notes how generous this wine has been from the beginning, but has developed further opulence and depth in bottle.  This is a beautiful wine: the nose is intense, exuberant with dark fruit and a satisfying herbaceous edge. Although the blackcurrant and black plum fruit is beautifully ripe and smooth, there’s bright acidity that brings gorgeous freshness – making for a lithe and vibrant palate. The tannins are round and sleek, lending effortless structure, while there’s a saline, savoury edge to the long finish.    Explore all current Ad Vivum listings, including a mixed case of 2016, 2017 and 2018, or read more about California   

Since 2007, Chris Phelps has been working with just 1.5 acres of Cabernet Sauvignon in Sleeping Lady Vineyard in Yountville. The resulting wine is Ad Vivum, a beautiful expression of this special site. We sat down with Phelps to taste through a mini-vertical of the project

Tasting Ad Vivum: 2016-2018 

Chris Phelps never really meant to start his own winery. But fate had other plans.  Wine had always been part of life, just in the background. Growing up in Livermore, east of San Francisco, Phelps’s parents would buy a ton of grapes from Napa or Sonoma, and make wine each year for themselves. Phelps even dug out a cellar by hand for them as a teenager. Nevertheless, when he set off for UC Davis, it wasn’t to study wine, but medicine. To pay for university, he took a job as a firefighter in Idaho (“kind of scary but super fun,” he tells me). By chance, he met a wine-geek friend, one who eventually convinced him to switch from pre-med to oenology. At Davis, he happened upon Alain Bertrand – one of the first scientists to use gas chromatography to delineate the different aromatic compounds in wine. The Frenchman didn’t speak much English, and Phelps spoke French – so they ended up becoming friends. Bertrand suggested Phelps attend the University of Bordeaux for a year after graduation. There, Phelps tells me, everything “started to fall into place”. Until then, wine had been intellectually interesting – but, during his time in France, it became much more.   There, another professor pushed him to apply for an internship – just in time for the 1982 harvest, a vintage that would turn out to be legendary. He already had offers from both Ch. Simon (Barsac) and Ch. Beauregard, but then was given the opportunity to interview with JP Moueix (of Pétrus). Unusually Christian Moueix insisted on joining the interview himself, alongside winemaker Jean-Claude Berrouet, and promptly gave him the job. The confident young American, however, said he’d think about it – and set off for a holiday in the south of France with his fiancée. Little did he know that Moueix had just bought a swathe of vineyard in Napa – and was planning for the future.  A few weeks later, Phelps was in Nice and bought three postcards from the Chagall museum – ready to make his decision about the three possible roads that lay ahead of him. He decided to take the position at Moueix, posted his rejections and acceptance, and carried on with his holiday. But, as harvest time approached, Phelps hadn’t heard anything back. He called Berrouet – only to find out that the French postal service had let him down, and the job at Pétrus had been given to someone else. It seemed like his luck had run out, but Berrouet said he might have another idea and would call him back in a few days.   While Berrouet couldn’t offer him anything as prestigious as Pétrus, he found Phelps a job at Ch. des Laurets in Puisseguin-Saint-Emilion – but he wouldn’t just be an intern, he’d be running everything. It was, Phelps said, a “trial by fire”, especially given his only hands-on experience to date had been six months at Louis Martini. He worked non-stop with just one cellar hand to help during the day, and managed to make it through the season.   When the wines were safely in barrel, he went to dinner at Christian Moueix’s house – where, sipping Champagne in the library, Moueix told Phelps about his plans for his Napa project, Dominus – and asked if he’d be the winemaker. “Of course, I said no,” Phelps tells me – recalling how the Frenchman opposite visibly sputtered at the American’s cheek (again). Phelps said he needed more money to live in Napa (and support his bride-to-be) – and more experience. Amazingly, Moueix agreed to let him start from 1984, given the 1983 vintage was set to be just a handful of experimental barrels, and to a pay rise. Off Phelps went, working around California and wintering at Pétrus before returning to lead the team at Dominus.   “We figured it out as we went along,” Phelps says, looking back on the early days of what is now one of Napa’s most prestigious estates. Today they might have the iconic Herzog & De Meuron winery, but things were much more rustic at the beginning – with a small team and little infrastructure. Phelps eventually moved on, joining Caymus in 1996 – but it’s what started happening after-hours, around his day job, that is interesting.  In 1990, Phelps met Larry Bettinelli at a Christian men’s retreat, and hit it off. It was only when they met up for lunch later that they realised they were both in the wine business, with Bettinelli a fifth-generation farmer who was growing grapes. Bettinelli wanted his vineyards to be the best in the valley – but he needed feedback on the fruit so that he could adapt his viticulture. He and Phelps hatched a plan: each year, Bettinelli would give Phelps a ton of fruit, trialling different clones, rootstocks, vine spacing and trellising, harvest methods, and Phelps would make a wine with it. The project was purely intellectual, so the two families drunk the wine themselves, and it also started being used as the altar wine at Phelps’s church (a much higher-grade communion offering than most). For two decades, they kept making tiny batches of their first-class “homebrew”, and Bettinelli became one of the valley’s best growers, working with an increasing number of sites around Napa.  Destiny seemed to abandon all subtlety in 2005. Phelps was hiking through the Sierra Nevada, leading a Scouts expedition, when they were struck by lightning. Two of the group died and Phelps was knocked unconscious. Unsurprisingly, it shook Phelps to the core. “Life is our most precious gift,” he says, “and if we use wine appropriately, it can enhance our lives.”  Two years later, Phelps was on top of a tank that had just been filled with crushed fruit from a relatively new Bettinelli site – and the smell was intoxicating. Following pure impulse, Phelps asked if he could – rather unconventionally – buy the tank’s contents, and Bettinelli said yes. Ad Vivum – inspired by the Latin “vinum” for wine and “vivere” to live, combined with “ad” which translates as “to” or “towards” – was born.  The vineyard was Sleeping Lady (previously Reese), the southernmost vineyard in Yountville, at the foot of the Mayacamas and on the southern end of the valley’s famous bench. There’s a flow of underground water that feeds a creek, with sufficient clay under the gravel and sand to retain water during the dry summer – and has, in Phelps’s words, a “beautiful ability” to self-regulate. Various other producers work with the vineyard, but his two blocks (representing a mere 1.5 acres) are right at the top of the vineyard, below a steep slope that aids the flow of cool air through the site at night. For him there was something special about these plots – producing fruit and wine with what Phelps describes as a “grace note”; it’s a whisper of something that takes the wine to the next level.  In a good year, production for Ad Vivum is 450 cases – but Phelps isn’t looking to grow. He makes one wine, from one site – and that’s the way he wants it to be. The wine is undoubtedly informed by his Franco-American roots, with an elegance, freshness and savoury structure that complements the plush Napa style. As he says, “I try to build wines that speak for themselves.”  Phelps’s – and Ad Vivum’s – story is one of happenstance. Or is it? With a man as devout as Phelps, it seems hard for anyone to believe it’s all an accident – and as Phelps himself says, looking back, it feels perhaps like it’s all part of a master plan.  Explore all current listings of Ad Vivum or read more about California
